An episode will be broadcast as part of BBC Two's festive schedule, with the rest of the episodes from the new Series 3 then being shown in early 2017.

The scheduling news was revealed in a Guardian article in which the creators discussed what scares them. Producer Adam Tandy confirmed the plan on Twitter, saying it was "100% right".

The new episode due to be broadcast this December is titled The Devil Of Christmas, which stars Rula Lenska and Jessica Raine alongside Shearsmith and Pemberton. First revealed earlier this year at the Starburst Film Festival, the episode is set around an alpine chalet and involves the horned "half-goat, half-demon" Krampus character from Austro-Bavarian folklore. Set in 1978, it has been filmed by the production team using old 1970s filming equipment as a homage to the era.

Speaking at the time of Series 3 being announced, Shearsmith and Pemberton commented: "We are most thrilled to have been handed the keys to another six No. 9s, and to have attracted such a glittering array of talent. We have reassured them that this time there are lots of happy endings and everybody makes it out alive. And like fools, they believed us."
